基于“色散-叠加”的多维度微博信息交互演化模型研究

“Dispersing-Superimpositing”-based Multi-dimensional Interaction Evolution of Microblog Information

已有微博环境中的信息传播研究主要聚焦于单个信息维度的分析,并未考虑多个不同信息维度之间的相互影响及其交互演化。本研究基于光学散射的思想提出微博信息的“色散-叠加”模型,用以描述符码信息、情绪信息、情境信息这三维度信息分量在微博信息传播中的交互演化方式,选取新浪微博中的一个事件来进行模型的验证分析。实验结果表明,微博中多维度信息的色散或叠加的转折点与事件演变发展具有密不可分的关系,且在事件发展的各个阶段分别对应着不同的主导信息。本研究不仅从更深层次为同一信息在微博中呈现的不同传播效果进行了全面阐释,还通过信息维度间的相互作用和交互演化规律为微博等信息媒介中的舆论预测及分析提供了理论与实践支持。

Most of the current research on the Sina Micro-blog focused on a single information dimension like emotion or context,and did not analyze the interaction between varied information dimensions during the communication process.Thus,in this study we proposed an information“dispersing-superimposing”model according to the optical dispersion to describe the impact within symbol,sentiment and context information dimensions and their dependent evolution on the Sina Micro-blog.An event from Sina Micro-blog was selected to demonstrate and verify the hypothesis of this study.The experimental results showed that the turning point of dispersion or superposition of multi-dimensional information in Weibo is inseparably related to the evolution of events.It was also found the dominant spread information component differed at each development stage of event on the micro-blog.This study not only comprehensively explains the different communication effects of the same information in Micro-blog from a deeper level(that is,the reason why information of certain dimensions in the information dissemination process is enhanced or ignored),but also provides theoretical support for the prediction of public opinion in the new media environment such as Micro-blog through the interaction between information dimensions and the law of interaction evolution.
